The sum of the numbers on the fifteenth row of Pascal's triangle is 215 = 32768.
64
The terms in row 29 are: 29Cr = 29!/[r!*(29-r)!] for r = 0, 1, 2, ... 29 where r! denotes 1*2*3*...*r and 0! = 1
The rth term of the 25th row is 25!/[r!(25-r)!] where r = 0,1,2,...,25 and k! denotes 1*2*3*...*k and 0! = 1 So 1 25 300 2,300 12,650 53,130 177,100 480,700 1,081,575 2,042,975 3,268,760 4,457,400 5,200,300 and then the same numbers in reverse order, all the way back to 1.
(1/2n-r)2+((n2+2n)/4) where n is the row number and r is the position of the term in the sequence
depends. If you start Pascals triangle with (1) or (1,1). The fifth row with then either be (1,4,6,4,1) or (1,5,10,10,5,1). The sums of which are respectively 16 and 32.

Sum of numbers in a nth row can be determined using the formula 2^n. For the 100th row, the sum of numbers is found to be 2^100=1.2676506x10^30.
The number of odd numbers in the Nth row of Pascal's triangle is equal to 2^n, where n is the number of 1's in the binary form of the N. In this case, 100 in binary is 1100100, so there are 8 odd numbers in the 100th row of Pascal's triangle.
The sum of the numbers in the nth row of Pascal's triangle is equal to 2^n. Therefore, the sum of the numbers in the 100th row of Pascal's triangle would be 2^100. This formula is derived from the properties of Pascal's triangle, where each number is a combination of the two numbers above it.
The sum is 24 = 16
If the top row of Pascal's triangle is "1 1", then the nth row of Pascals triangle consists of the coefficients of x in the expansion of (1 + x)n.
The 6th line in Pascal's Triangle corresponds to the coefficients of the binomial expansion of ((a + b)^6). It is represented as: (1, 6, 15, 20, 15, 6, 1). Each number is derived from the sum of the two numbers directly above it in the previous row. The entire 6th line can be indexed starting from 0, so it is often referred to as the 7th row.
The Fifth row of Pascal's triangle has 1,4,6,4,1. The sum is 16. Formula 2n-1 where n=5 Therefore 2n-1=25-1= 24 = 16.
1, 9, 36, 84, 126, 126, 84, 36, 9, 1
The sum of all the numbers in row ( n ) of Pascal's triangle is given by ( 2^n ). For row 10, this means the sum is ( 2^{10} = 1024 ). Therefore, the sum of all the numbers in row 10 of Pascal's triangle is 1024.
